<body>
<center><h1>SERVICE</h1>
<h2>Enter Service Details</h2>
<form:form method="POST" commandName="servDetForm" action="AddService">
<table style="appearance:dialog ">
<tr>
<td>Number</td>
<td><form:input path="xxx"/></td>
</tr>
<tr>
<td>Number</td>
<td><form:input path="xxx"/></td>
</tr>
<tr>
<td></td>
<td><form:button name="addService" value="Add Service">Add Service</form:button></td>
</tr>
</table>
</form:form>
</center>
</body>
